Report about hospital drug (5)
I believe the answer is:
bhang
'drug' is the definition.
(bhang is a kind of drug)
'report about hospital' is the wordplay.
'report' becomes 'bang' (I've seen this before).
'about' is an insertion indicator.
'hospital' becomes 'h'.
'bang' placed around 'h' is 'BHANG'.
(Other definitions for bhang that I've seen before include "cannabis" , "Leaves and shoots of hemp" , "Hemp-based narcotic" , "Narcotic used in India" .)
